Social dialect, the semantic barrier, and access to curricular knowledge

This paper introduces the theory of the lexical bar. It reports research studies conducted in England and Australia. A semantic barrier exists in the English lexicon that emerges from socio-historical factors and is reinforced by the socio-occupational orderings of contemporary society. This barrier separates the lexes of conservative peripheral social dialects from the lexes of dominant central dialects. It serves to produce differential attainment rates in education and to reproduce a social class-based division of labour in English-speaking societies.
